This causes a signficant (10%+) performance hit. On

With pretty trivial user mode programs being able to crash the kernel due to the ref counter widths in Xen being more narrow than in Linux, I started an attempt to put together a kernel side fix. While addressing the plain hypercalls is pretty strait forward, dealing with multicalls (both when using them for lazy mmu mode batching and when explicitly using them in e.g. netback - the backends are

Is it intentional that - under SVM, 32-bit guests can freely set EFER.LME - under VMX, 32-bit guests can''t access EFER at all? Thanks, Jan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
